To all whom it may concern: 7

Be it known that I, CHARLES NORTH, of

Colorado Springs, in the county of El Paso Roasting and Warming Peanutsor Coffee, of

which the following is aspecification.

My invention consists principally of a hollow drum or cylinder having ahinged lid, a flange on the inside, and a flanged opening in the end ofsame corresponding toa'n opening in the end of the jacket covering theroaster. Above this cylinder I have constructed a hopper with aslide-gate, by means of which the cylinder may be almost instantlyfilled and Without allowing the heated drum to cool. Under this drum isa drawer with a perforated bottom, into which the roasted product is(lumped. This perforated bottom allows all dirt and trash to fallthrough and leaves the nuts or coffee clean and ready for market.Through an opening in the end of the drum and a corresponding opening inthe end of the jacket samples of the product may be allowed to escapewhenever the operator may think necessary. It will be seen that in thisdevice, however much the opening'in the end of the jacket maybe leftopen, the opening in the cylinder is closed and the cylinder practicallyair-tight except when directly opposite the opening inthe jacket, thuspreventing the escape of any considerable amount of heat. The cylinderis to be revolved by means of a crank, as shown in the drawings, or bymeans of any suitable motor or power.

The beneficial objects which I seek to attain by my improvement is toprovide an inexpensive roasterin which nuts or coffee may be evenlyroasted with a minimum expense and a maximum speed and in which thefinished product will be left clean and ready for the market. In orderto attain these objects, it is necessary to have a mechanism in whichthe heat will be evenly distributed, the substance constantly agitated,and from which samples may be frequently or continuously taken.

In the accompanying drawings, Figure 1 is a front elevation showing thehopper and internal construction. Fig. 2 is an end View with thecovering removed and showing the internal construction. Fig. 3 is avertical section from front to rear and shows the position of thevarious parts while it is in the act of being-filled. Fig. 4. shows .adetached piece of the end of the 'jacketyh'avingin it an opening with asliding cover. 7

Throughout the several figures like characters refer to like parts.

Referring to the details of the device as set out in said drawings, 1represents the hollow drum or cylinder; 2 represents the hinged lid onsaid cylinder. 2 2 represent the hinges on said lid.

3 3 represent the rod extending through the cylinder and having bearingsat points 3 3 5 represents the drawer or receptacle. under saidcylinder, into which the contents of the cylinder is to be dumped. Thisdrawer hasaperforated bottom,(shown by5",)through which dirt and trashmay be allowed to escapeand to fall on thetight bottom 15. 6 representsthe hopper, and 13 the gate to said hopper.

5 5 are handles on the drawer 5.

7 is a pipe or gasolene-jet by means of which the contentsof the drawer5 may be kept warm.

7 is a cock to be used to regulate the jet 7.

8 is a perforated pipe extending horizontally under the cylinder1,'whichfurnishes a sufficient num'ber'of jets to properly roast thecontents ofsaid cylinder. I

8* is a cock to be used to regulate the flow of gas or gasolene in th epipe 8 1.0 is a gasolene-tank from which gasolene is supplied to thegenerator 12.

' '9 is a flanged opening inthe end of the cylinder 1, the edges ofwhich are turned out, so that they almost come into contact with thejacket. When the cylinder is revolved until this opening is at thelowest point the jacket near the top, to be constructed of sufficientsize to allow the lid 2 to be opened to it.

The method of operation is briefly de scribed as follows: The hopper isfilled with the material to be roasted. The lid 16 is opened and thecylinder 1 revolved until the lid 2 appears at the opening. The lid 2 isthen opened and thrown back, as shown in Fig. 3. The cylinder is thenturned back until the opening in it is under the hopper and the gate inthe hopper drawn. When the cylinder is properly filled, lids are closedand the roasting carried on. After the samples indicate that thesubstance is sufficiently roasted thelids are again opened and thecylinder turned forward until gravity opens the lid 2 and the contentsof the cylinder is entirely emptied.

This device may be adapted either to wholesale or retail work. Theprincipal advantages over existing devices are speed in filling andemptying, no loss of heat, and the ease with which samples may beobtained.

Having thus described my invention, what Iconsider new, and desire tosecure by Letters Patent, is-

The combination in pean ut and coffee roasters, of a metallic cylinderhaving an inside flange and a flanged opening in the end, a metallicjacket having a hinged lid and an opening corresponding with that in thecylinder, substantially as described and for the purposes set forth.

In testimony whereof I have hereunto affixed my signature in thepresence of two Witnesses.

CHARLES NORTH.
